A positive electrified charge control agent comprising a silicon complex compound of an effective component represented by the following chemical formula (I) and/or chemical formula (II)
(in the formula (I) and formula (II), [D-(SO3)2]2- is a bivalent anion of an organic acid having at least two sulfonic acid groups, p is 0 or 1, B is a bonding line when p is 0, B is a carbon atom or a nitrogen atom when p is 1, J is a carbon atom or a nitrogen atom, A is an organic group which forms a ring with (B)p and J, both of R are same or different to each other and are an organic group, and these both of R are independent or form a heterocyclic ring). A positive electrified toner for developing an electrostatic image comprises the positive electrified charge control agent. A charge control method of the positive electrified toner for developing the electrostatic image comprises α step for making the toner positively electrified by friction.
